Function of One Variable

Based on the concept of maximum of function of one variable and relevant knowledge as well as the concept of directional derivative , the paper puts forward the necessary conditions for the existence of extrema of function .

运用一元函数极值的概念和有关知识，并联系方向导数的概念，得出了多元函数极值存在的几种必要条件。

So , remember , if you have a function of one variable , that means you have a quantity that depends on one parameter .

如果你有一个一元函数，那意味着你有一个依赖于一个参数的量。

And so really , this is only a function of one variable here Linearly , with respect to one variable .

所以总压强只是，一个变量的函数，一个变量的线性函数。

If we had a function of one variable , we would decide things based on the second derivative . And , in fact , we will see tomorrow how to do things based on the second derivative .

如果我们有一个一元函数，我们将根据它的二阶导来判断，明天我们会看到二阶偏导能够做什么。

Using the experimental mathematics method combining the theory of analytic function of one complex variable with computer aided drawing , this paper researches on the structure topological inflexibility and the discontinuity evolution law of generalized Mandelbrot-Julia set .

采用复变函数理论和计算机制图相结合的实验数学方法，作者研究了的广义M-J集内部的结构拓扑不变性和裂变演化规律。

The properties of derivative function for functions of one variable

一元函数导函数的性质

The study of analytic function spaces of one complex variable has a long time , and obtains a lot of complete results .

单复变数解析函数空间H~p、D~P等的研究已有很久的历史，并且也得到了许多比较完美的结果。

Finally , the H-B interpolation problem of a function of two variables can be reduced to that of a function of one variable .

最后，把二元函数的H-B插值问题化为一元函数的H-B插值问题。
